FASTENING HINGE.

Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filed August 18, 1920. Serial No. 404,390.

T 0 all whom it may concern:

Be it known that 1, JAMES A. BRADY, a citizen of the United States, and resident of Hoboken, in the county of Hudson and State of New Jersey, have invented a new and Improved Fastening Hinge, of which the fol lowing is a full, clear, and exact description.

In connection with display stands, and more particularly that type shown in the patent granted to me under date of October 28, 1919, No. 1,320,310, it is well understood that diiliculty has been experienced in providing a securing means for connecting the individual parts of the stand together, in such a manner that they will be either rigidly held or capable of movement freely with respect to one another.

lVith this in mind, I have constructed a securing hinge more particularly applicable to devices of this class, but which is not necessarily limited to this adaption.

Reference is had to the attached sheet of drawings as illustrating one practical embodiment of my invention as applied to a stand of the character mentioned, and in which Figure 1 is a perspective view of a stand showing the fastening hinge in applied position.

Figure 2 is an enlarged sectional view taken along the lines 22 of Figure 1'.

Figure 3 is a similar section taken along the lines 3-3 of-Figure 2, and

Figure 4 is a sectional view taken along the lines 4-4 of Figure 1.

In these views the reference numeral 5 indicates the risers and tread of a stand constructed in accordance with the patent afore-mentioned, which are' supported by means of panels, 6, 7 and 8 of a height corresponding to the tread which they underlie, the panels 7 and 8 being hingedly secured as at 9, to each other, the panel 6 being in turn hingedly secured (not shown) to the under side of the first tread.

By this construction, it is possible to fold the risers and tread 5 one upon the other, the panels 6, 7 and 8 being folded correspondingly, subsequent to which the latter are swung to a position underneath the lowermost tread so that one compact unit is formed.

The problem which is now confronted consists in properly connecting the supporting panels, 6, 7 and 8 with the corresponding risers and tread portions of the display stand in such a rigid manner that the same are capable of supporting a great amount of weight, these connections being however of such simplicity as to permit of their uncoupling,'so that the entire stand may be collapsed in the manner aforedescribed.

With this in mind, hinge straps 11 and 12 are associated by means of screws or other suitable securing devices 10 with each of the risers and tread portions 5, these straps 11 and 12, being swingingly secured together as at 13. It is now to be noted that contrary to the conventional construction, the strap 12 terminates at a point short of the point of contact of the risers with the tread 5, as has been clearly shown in Figure 3. Accordingly' the point of connection 13 is at a position correspondingly short from its point of contact, and with this in View, and for a purpose hereinafter more fully specified, the strap 11 is extended outwardly and bowed, as has been indicated at 1 1, its end portion being bent inwardly connecting with the strap 12.

Thus it will be appreciated that a hinged connection is provided which will permit of the risers being folded upon a tread in such a manner that the lower edge of the riser may project into the bowed portion 14 of the strap 11. Now to provide means which will permit of the rigid securing of the members, one with respect to the other, the bowed portion 14 of the strap 11 is preferably formed with an extended portion 15, which is provided with an opening in which a stud 16 is rotatably mounted.

The stud 16 is formed with a knurled head 17, and a screw threaded projecting shank 18, which latter is adapted to extend into a screw threaded socket 19 secured to the outer faceof one of the panels at a point dlrectly adjacent the stud when the parts are fully extended. By virtue of this construction, when the parts have been extended as aforestated, it will be possible to cause an engagement between the stud 16 and socket 19, and accordingly between the risers and tread portions 5 and the panels, so that noltrelative movement of the parts may resu In this connection it is to'be noted that the extended portion 15 is cut away, as has been indicated in Figure 2, so that the engaging portion 20 exists, which latter is adapted to bear against the socket 19 and act as a guide for the positioning of the similar in all respects to the socket aforedescribed, is attached to the under side of the uppermost tread at a point preferably adjacent its rear edge.

A member, including a screw threaded I shank 21 has this portion of its body extending into the socket 19, to the rear of which portion a knurled part 22-is provided, the body of the shank being further extended and terminating in a head 23, which is re-' tained by an engaging portion 24 associated with the upper edge of the panel 8 in such a'manner that the shank 21 is capable of r0- tation. r a

. It will nowbe understood, that the stand may be set up in the conventional manner,

and the hingesfastened, as has been aforedescribed, subsequent to which the shank 21 may be introduced into the socket 19,

. associated with the under side of the uppermost tread, and upon the shank being turned withrespect to the socket, the screw'threads will inter-engage resulting in a firm retention of the panelwith respect to the tread.

7 While my fastener is particularly applicable for use in connection with a display stand, it will readily be understood that the same might be adapted to any number of uses, and that the construction of this fastenor might be varied within the scope of my claims, which are- 1. A fastening hinge includingin combination with a display stand, which comprisespanels, and risers and treads supported by said panels, of means adapted to movably connect the risers and treads with each other, and further means forming a part of said first named means and adapted to engage the panels supporting said risers and treads for rigidly connecting said elements together. i

2. A fastening hinge including in combination with a display stand, which comprises panels and risers and treads supported by said panels, of means adapted to movably connect the risers and treads to each other, and further means carried by said first named means, and engaging said panels, to connect said risers and treads and panels rigidly together.

3. A fastening hinge including in combination with a display stand'which comprises panels, and risers and treads supported by said panels, of a pair of straps hingedly connected to each other, one of said straps being formed with an enlarged portion adjacent its point of hinged connection with said second strap, and fastening means extending through said enlarged portion and adapted to engage one of said panels for rigidly retaining the whole in assembled condition.

4:. A fastening hingeincluding a pair of straps adapted to be secured to two elements movable with respect to each other, and a screw threaded stud rotatably secured to one of said straps and adapted to engage a third element movable with respect to the first named elements.

5. A fastening hinge including a pair of straps hingedly secured one to the other and being adapted to connect together two elements movable with respect to each other, one of said straps being bowed adjacent its point of hinged connection, an enlarged portion forming a part of said bowed portion and disposed adjacent the point of hinged connection of said straps, and a stud projecting transverselythrough and rotatably mounted within an opening in said enlarged portion.
